Australian Matthew Ebden has leveled the match against France's Giles Simon and it's little surprise with points like this!

"Time!"

But Rafael Nadal finds a few more seconds to rattle down a couple more practice serves.

He'll get this one under way.

Benoit Paire double faults first up, which absolutely won't improve his mood.

This is quickly slipping away from the Frenchman. Error after error hands Juan Martin del Potro two break points, although Paire regains his composure to batter an ace down the T, another missed forehand hands Del Potro the break.

Bumped into former England cricket captain Andrew Strauss on his way to the Royal Box at Wimbledon - he knows a thing or two about leading his nation to glory.

"Obviously I'm here to watch the tennis but it is impossible not to be thinking about the football and we'll be getting loads of updates along the way," he says.

"It's do or die. I think they're in a really great place, they look confident and don't feel or look like they're being weighed down by expectation.

"It's a case of going out there and winning it, and not hoping not to lose it."

So the big question... will they win it? "Yes! I think they will."

Juan Martin del Potro, who looks like he's finding the whole thing slightly amusing, races through a hold to love.

Incidentally, this was the look on the face of Benoit Paire's coach as his charge was ranting away to himself. Paire's still grumbling in between points.

Alex de Minaur is all smiles, the 19-year-old said he was "living the dream" earlier - and what a dream.

Just the small matter of the world number one at the other end...

I have no problem with animation, you want characters, but if there are insults he's got then take control. I don't understand what he's going on about. He didn't lose points by the umpire overruling.

Oops, that's a fine incoming from Benoit Paire.

The Frenchamn slams his racquet down on the chair in sheer annoyance after Del Potro claims the set, then has what I'll politely describe as a rant towards the umpire.

Paire's still yelling away to himself as he changes his shoes.

And all those sporting stars are about to see another in action...

Rafael Nadal is first up on Centre Court as he takes on teenage Australian Alex de Minaur.

Another stonking great serve from Juan Martin del Potro hands him a couple of set points.

Oh, and Paire blazes a backhand into the net to hand the Argentine the second set!

Benoit Paire loses his footing and yet still, despite being on his knees, manages to hammer a forehand winner down the line.

Oh! A little bit of net play and it's Paire who volleys the eventual winner.

Winter Olympians Amy Williams and Lizzy Yarnold are in the house! They get a warm Centre Court reception.

They're joined by boxers Nicola Adams, Carl Froch and David Haye.

The names continue. Dame Jessica Ennis-Hill, swimmer Adam Peaty... some serious sporting genes floating around the Royal Box today.

Golfer Tommy Fleetwood's also among them, as is former Masters champ Sergio Garcia and American Matt Kuchar.

There's England stars of the cricket and rugby variety, Andrew Strauss and Chris Robshaw, as well as Wales legend JPR Williams.

Be some competition if they broke out into a spontaneous mini-Olympics on Centre Court.

And then there's Sir Bobby Charlton. Brilliant.

Benoit Paire hurries his way through a forehand, and nets.

Juan Martin del Potro slowly stomps his way around court at the change of ends, and edges further in front with a lovely one-two punch.

Benoit Paire flunks a forehand into the net, then gets his own back with a furious swipe out wide that the Argentine can't get underneath.

Benoit Paire lets out a huge scream of frustration as he hoicks a forehand long.

Ooft. A huge serve from Del Potro rips through Paire's defences. That won't cheer him up too much.

Big forehand from Del Potro, but it's into the net, and the first point of the tie-break goes Paire's way.

These two are falling about all over the place, but Juan Martin del Potro has managed to stay on his feet long enough to force a tie-break against Benoit Paire.

This match has been really enjoyable so far, grass-court tennis at its best - Juan Martin del Potro leap into another dive to try and reach a Benoit Paire passing shot, but cannot get enough purchase.

Here's a touching moment from earlier...
